Restricted Stock Unit (RSU) financial

"Each RSU represents a contingent right to receive one share of Sphere 3D Corp. common stock."

A restricted stock unit (RSU) is a promise from a company to give an employee company shares (or cash equal to their value) at a future date if certain conditions are met, such as staying with the company or hitting performance targets. For investors, RSUs matter because when they convert into actual shares they increase the number of shares available and can create selling pressure as employees cash out—think of them as a future paycheck paid in company stock.
